More than 1 billion people are watching YouTube videos every month, and with good reason. YouTube is amazing.

In addition to being a great place to watch adorable kids or crazy cats, it's also an incredible educational tool. With just one click, you can learn how to cook or speak Spanish, fix your car or work out a trigonometry problem, often for free and often by academics.

But there's a dark side to YouTube's educational videos. Evil-minded hackers are teaching countless people how to remotely invade your home, and secretly record your intimate moments.

In fact, you're in real danger of being enslaved by hackers who can take over your webcam. You won't know about it until an email from these evil hackers pops up out of nowhere.

They'll demand money or they'll release your private videos to the world. Worse, some of these hackers want to make you their slave by keeping you hostage. They might tell you or your kids or grandchildren to perform acts on video, or else.

This happens every day, including in 2013 to Miss Teen USA. Cassidy Wolf's hacker secretly took control of her webcam for months. He ultimately demanded that she do whatever he told her to, or he'd post her private videos. She called the cops, who caught her cyberattacker.
